[PATCH net-next v2 0/6] vxlan: cleanup and IPv6 link-local support

[Matthias Schiffer <mschiffer@universe-factory.net>]

Running VXLANs over IPv6 link-local addresses allows to use them as a
drop-in replacement for VLANs, avoiding to allocate additional outer IP
addresses to run the VXLAN over.

Since v1, I have added a lot more consistency checks to the address
configuration, making sure address families and scopes match. To simplify
the implementation, I also did some general refactoring of the
configuration handling in the new first patch of the series.

The second patch is more cleanup; is slightly touches OVS code, so that
list is in CC this time, too.

As in v1, the last two patches actually make VXLAN over IPv6 link-local
work, and allow multiple VXLANs wit the same VNI and port, as long as
link-local addresses on different interfaces are used. As suggested, I now
store in the flags field if the VXLAN uses link-local addresses or not.


Matthias Schiffer (6):
  vxlan: refactor verification and application of configuration
  vxlan: get rid of redundant vxlan_dev.flags
  vxlan: improve validation of address family configuration
  vxlan: check valid combinations of address scopes
  vxlan: fix snooping for link-local IPv6 addresses
  vxlan: allow multiple VXLANs with same VNI for IPv6 link-local
    addresses
